Tactical Life posts that the military is changing to the 6.8 in SAW and M4

Look back to observations by LRRPF52 on this topic. This is clearly not a 5.56 replacement, but is more likely a candidat to to eventually replace the 7.62 NATO.

You are clearly mistaken. NGSW = Next Generation SQUAD Weapon.

The 6.8mm NGSW-R and NGSW-AR are meant to replace the 5.56mm M4 carbine and M249 machine gun in the infantry rifle squad.
